PID Control Demonstration

PID Controller Simulator OR Hydraulic Position Controller Simulator

This is a PID controller simulator and runs on soft PLC platform. The backend code is developed in IEC61131 PLC software development languages. The Codesys V2.3 software has IEC61131 PLC development environment with frontend tools. This is very usefull application for studying PID control system. After running the software you can adjust P, I, D values online to optimize controller. You can also change position set point. In auto mode if Safe Stop button is pressed then the PID controller adjusts pressure inside the chamber to equilibrium pressure, so that the weight stops at its present position. With permutations of PID values you can check working of PID controller in Overdamped state or Underdamped State or Critically damped state. Real time graph of set pressure and actual pressure can be observed.

Also to have complete feel of hydraulic system you can put the system in manual mode. In manual mode you will have to control spool position in the range (-1.0000 : 0.0000 : +1.0000) for controlling weight position.

Scope of supply from Q-Log Controls and Systems

Codesys V2.3 complete software

This is a integrated development platform with IEC61131 PLC and visualization. PLC programs can be developed in IL(Instruction List), LD(Ladder Diagrams), FBD(Function block diagrams), SFC(Sequential Function Charts), ST(Structured Text) and CFC(Continuous Functin Charts). In visualisation you can develop User Graphic Interface required for your application.
